From afdea8bac5e80362459940e18e705d792e677a57 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Fri, 10 Jun 2011 08:58:42 -0300 Subject: [PATCH] [media] media: vb2: reset queued_count value during queue reinitialization MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit queued_count variable was left untouched during the queue reinitialization in __vb2_queue_cancel, what might lead to mismatch between the real number of queued buffers and queued_count variable.
